Solution
Cost price = Rs.800
The cost of 3/4th of rice = 3/4 *800=Rs. 600
10% of it = Rs.60
Its selling price = Cost price-loss=600-60=Rs.540 ...(1)
The cost of remaining rice = 800-600=Rs. 200
10% of it = Rs. 10
Its selling price = Cost price+gain = 200+20=220 ...(2)
From (1) and (2),
Total selling price = 540+220=Rs. 760
Total Loss = Cost price-Selling price=800-760=Rs.40
Cost price = Rs.800
The cost of 3/4th of rice = 3/4 *800=Rs. 600
10% of it = Rs.60
Its selling price = Cost price-loss=600-60=Rs.540 ...(1)
The cost of remaining rice = 800-600=Rs. 200
10% of it = Rs. 10
Its selling price = Cost price+gain = 200+20=220 ...(2)
From (1) and (2),
Total selling price = 540+220=Rs. 760
Total Loss = Cost price-Selling price=800-760=Rs.40
